Question

State any excluded values of a domain and identify the type of break in the graph at the value of x

f(x)=x+7/x-2

Answer 1

The excluded value in the domain is x = 2 because the denominator of the rational function becomes zero at this value of x, which results in division by zero.

At x = 2, there is a vertical asymptote, which means that the graph of the function approaches positive or negative infinity as x approaches 2 from either side.
